I’ll assume it’s not a PSN+ subscription issue…
DLC’s certainly doesn’t make troubleshooting easier. I was fortunate to find a cheap disc… (That worked properly. Knock on wood.)
Not a “computer wiz” so I’m a bit at loss. I’ll ping @VaultHunter101 . See if he can direct you to the “troubleshooting tickets” thing. Petty sure he’ll find you’re post anyways but just in case.
